We have mains shower off combi boiler and the flow rate is quite high
due to high mains pressure. I've measure about 9 l/min.

I'm looking at reducing the flow rate and have found for instance this
screw in flow limiter

Yes - I think you'll like this:

https://www.bes.co.uk/products/099.asp

Part # 17527

You can replace the isolator(s) with this and select a cartridge to
adjust the flow rate as you wish.

I have several to stop water splash back in the basins due to high mains
pressure.

I 'regulate' the mains pressure (okay, flow) throughout the house by
only opening the mains cock by something like three quarters of a turn
(also means I can cut it off very quickly, if necessary). Can anyone
here tell me if that's a bad way of going about it? It has never caused
me any problems, but maybe there's something I've missed?

Not really - except it can generate noise at the valve.

Oh, right. Fortunately, it doesn't do that here.

This is the sort of thing water companies give away free - well, it's
included in the bills, at least. For example:

https://www.savewatersavemoney.co.uk...aving-products

You'll have to check your own supplier.

These work well and do not create noise.
Others will be available, sold as Economisers.
Easy to fit - or remove.

You can fit a pressure limiting valve straight after the stop cock.

Some appliances (in our case a water softener) have a maximum safe working
pressure and require a limiting valve if pressure is any higher.

6 bar is quite a common max pressure for things like inline water heaters.

I fitted a "Mira Eco" shower head some 10(?) years ago with the
intention of being able to run 2 showers off the combi at the same time.

On the product chart is shows a flow of around 6.5(ish) litres per
minute at 2 bar but it's a very flat line from about 4 litres at 0.5 bar.

Just seen this line in the booklet:
"To cap the flow rate at a maximum of 7 litres per minute, or to reduce
any vibration caused by certain water systems, an optional flow
regulator is provided. If required, install the flow regulator between
the shower outlet and the hose, as illustrated."

Had to fit the reducer washer in ours as it did indeed vibrate without
it. (running around 3.5 to 4 bar)

The real benefit of the shower head is it whacks a load of air in with
the water so a low flow still makes for a shower that has the apparent
water volume of a high flow.

Ignore the manufacturers price. I think I picked one up for around £17
on fleabay.
Highly recommend it.

Cheers
Pete

Plastic disc with a small orifice in it iirc...

When dealing with extremely high water pressure at my parents' house in
France (so high it hurt to take a shower), we drilled a 2 or 2.5mm hole
in a 5 centime piece (it was a long time ago!) and simply trapped that
between the shower hose and the valve.

Mmm clunky :-)
The mira type was, as I said, a disc like bit of plastic to insert
in the shower hose/valve connection, invisible once installed....

Thanks all for replies. A couple of comments - I don't want to reduce
pressure throughout the house and especially where the outside
taps/hoses are so turning down the stop cock or putting a pressure
limiter in line at the input is not a preferred solution.

Plumbing at the shower is all behind boards so can't get there.

So for the moment I have taken up the advice of several here to get a
free shower flow regulator and preliminary tests show a 15% reduction
in flow rate. If after a while we feel that isn't enough I'm tempted
to go for an adjustable device:

At one place with a new combi, the boiler goes out if shower flow is reduced.
